j: a citizen of the UnitedStates, and: resident of Akron, in: the county of Summituand and useful lmprovements'in Safety Devices for Punches, of whichtheifollowingis a specification. i

for punchesand otherrnoving Inachine elements; its object being to provide a guard oi simple and rellable UOIlStI'llC'tlOIh which can be=bodilymoved into and out of operative relation to said elements, and, which guard has provisionwhereby access can be had to the interior of the structure when it is in operative position.

The invention has been more especially designed for usein connection with the book-positioning mechanism 01: machines for assembling matchebo'oks, such, for example,

as illustrated in Letters "Patent of the United States No. 1,217,991, dated MarchG, 1917.

Said mechanism"comprises an oscillatory cylindrical head, or turret, having-intersecting passages extending diametricallytherethrough at right angles to each other, which passages receive match-books successively from an adjacent machine and position them beneath vertically reciprocating punches operative to eject the books into an underlying receptacle. The present device is designed to encase the punch mechanism during the operation of the machine and fin ers of the attendant.

f The invention comprisesa casing which is hingedly mounted adjacent the moving elementsfso as to be movable into andout of liousine relation thereto, said casing including a door or doors-that may be opened or closedwhen the casing is 1n hous ng posi tion.

The invention alsocomprises features of 4,5 construction which will be hereinafter described and. claimed. In the drawings y Figure 1 is aside elevation of the guard device as appliedto the punch mechanism of a book-match assembling machine, only for the.

The improved guard-device in its pre-I iterred form comprises a an elongated casing constructed to provide a generally trianguing also two curved doors 13 which are hinged, as atla, to the respective longitudinal edges of the bodyll for swinging movement in opposite directions to each other in order to open or close the front and forward sides of the casing; Preferably the front of the doors, when closed, provide an open sight space 15 therebetween; but ifdesired the doors maybe extended to'close the front of the casing entirely. The lower rearward end of the body .11 is connected to the, bracket 10 by means of a hinge 16, sov that when-the doors are swung open, as indicated be bodilyswung rearward inwa manner to uncoverthe punch mechanism and thus fac litateits inspection, adgustment, repair or with upstanding lugs 17 which are resiliently coupled by! a retract ng spring 18 whlch assumes a positlon forward and rear.

closed and opened, respectively, as seen in ing provided at its lower or receiving end with a bracket structure 10 in the spaced i by the dotted lines in Fig. 2, the casing can Fig. 2,-and thus tends not only to hold the doors in closing position when they: are shut," ut. also tohold theininopen position when they are opened. i 1

When the guard-device is in its up-standing position and the doors are closed, the.

2. In a safety-device for moving machine elements, a support adjacent'said elements, a casinghingedly mounted on said support and movable into and outof housing'relationto said elements, saidcasing including two oppositely-disposed swinging doors that may he opened or closed when the casing is in housing position, and resilient means op era-tive to maintain them in either open or closed position.

0. In a satety-device for moving machine elements, a casing COIJIPl'lSlHg a trough- I shaped body, a cap on said body, two doors hinged to the respective longitudinal edges of said body, and a spring resiliently connecting said doors and operative to maintain them in either open or closed position.

4. The combination with a match-book positioning element and reciprocating ejecting, punches co-acting therewith, of a casing hingedly mounted adjacent said punches and movable into and out of housing relation thereto, said housing including a door that may be opened or closed when the easing is in housing position, and resilient means operative to maintain said door in either open or closed position.

Signed at Barberton, in the county of Summit and State of Ohio this 7 April A. D. 1921.
